Diagram of the difference of phase of the components of Light reflected in Air from Diamond 
(according to Jamin’s experiments). 
The black line is the theoretical phase curve; the crosses represent .Iamin’s experimental results. 
DIagi’am of ratio of intensities of Light reflected in Air from Diamond (according to Jamin’s 
experiments). 
The black line is the theoretical curve ; the crosses show .Jamin’s experimental results.
